WINDING ATTACHMENT FOR GRAPHOPHO'NES.

SIECIFIGATION formingpart of Letters Patent No. 692,783, dated February4, 1902. Application filed March 28, 1901. Serial No. 52,613. (Nomodel.)

T0 at whom it may concern:

Be it known that I, WILLIAM E. DYRE, a citizen of theUnited States,residing at Takoma Park, in the District of Columbia, have inventedcertain new and useful Improvements in Winding Attachments forGraphophones; and I do. hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. p Y

My invention relates,primarily,to sound recording andreproducingmachines, in which class are included phonographs,graphophones, gramophones, and a variety of musicboxes actuated byspring-motors. w

More particularly stated, the invention relates to means for energizingor winding the motors of such instruments, its object being to efiectthis winding with the least possible expenditure of time and physicalexertion by the substitution of my winding attachment for the keys andcranks heretofore employed. {Beth keys and cranks have always beenregarded as unsatisfactory e'xpedients, not only because of theirtedious and laborious opera tion, but also'because of theircomparatively uncertain action. The former frequently slip from thefingers during the Winding process, the latter as often becomeaccidentally detached from the winding-shaft, while both are exceedinglyslow in the performance of their respective functions. To overcome thesedifficulties, I have invented and produced an attachment forgraphophones and similar instruments, whereby their actuating-motors maybe speedily and conveniently wound or energized by the rapid rotation ofa drum applied to' the winding-shaft of the motor.

Further characteristic features of the invention comprise a cord orother flexible bandsecured to and coiled upon said drum as a means ofrotating same in one direction, a pawl and,

ratchet interposed between said drum and shaft for transmitting powerfrom the former to the latter, a recoil-spring for rotating the drumreversely and rewindin g the cord aforesaid, and a back plate of novelconstruction designed and adapted to engage the motorframe and steadythe attachment in operative relation, all as will hereinafter more fullyappear, and be particularly pointed out in the claims following.

In the accompanying drawings, which form part'of this specification, andwhereon corresponding letters of reference indicate like parts in theseveral views, Figure 1 illustrates in perspective'a graphophone withmyinvention attached thereto in operative relation. Fig. 2 is a planview showing graphophone reproducing mechanism, the motor for drivingsame, its governor, and finally my winding attachment applied to themotor-shaft. Fig. 3 is a segregated view in perspective illustrating inrelative arrangement the following elements or parts of the invention-t0wit, an attaching hub, a back plate, a recoil-spring, the main drum, agravity-pawl, and a ratchetwheel. Fig. 4 is an end elevation wherein theratchet-wheel is partly broken away, disclosing a pawl for engaging anddriving said wheel during each' forward rotation of the drum. Fig. 5 isa vertical central section of my invention, taken on the line 5 5, Fig.4:. Fig. 6 illustrates in endelevation a modification of the inventionpartlybroken away to disclose an external ,rat'chetwheel andspring-pressed pawl. Fig. 7 is a vertical central section taken on theline 7 7 Fig. 6. Fig. 8 Ba perspective view of modified back plateappearing in Figs. .6 and 7..

, Reference, being had to the drawings and letters thereon, A representsa graphophonebase or bed-plate surmounted by a suitable frame B and bysound-reproducing mechanism comprising a reproducer O, record-mandrel D,and horn E -of usual construction. Thereproducing mechanism is driven bya spring-motor F, speed of the latter being controlled by a governor G,all of usual construction, and mounted in frame 13, through whichprojects the winding-shaft H of the motor,

, as clearly illustrated by Fig. 2.

Detachably secured to the winding-shaft H is a hub or nut I, having oneor more radial pockets 0. in its periphery to facilitate adjustment andremoval thereof by agency of. a wrench pin or nail. (Notshown) The outerportion of huh I is reduced, as at b, and upon this as a journal-bearingis loosely mounted the moving parts of the invention. Bypreferencejournal I) is shouldered at c and terminates in an outer externalscrew-thread cl for purposes that will later appear.

Rotatably mounted upon journal I) is the main drum Jof the attachment,comprising peripheral flanges e e, a central web or partition f,dividing the drum into front and back pockets or compartments g h,respectively, and a dru m-seat 1', projecting from the center of webfthrough the pocket h, as shown by Figs. 3, 5, and '7. Secured to theperiphery of drum J is the operating or winding cord K, same beingattached at a point in its length intermediate of its ends, normallycoiled upon the drum, projected therefrom in opposite parallel lines,and finally fitted with finger-rings jj, as indicated by Figs. 1 and 2.Obviously this element of the invention, herein designated as cord orcords K, may be of any flexible material or configuration adapted toperform the functions of that shown and may be secured in any approvedmanner-as, for example, by lacing same through radial openings hh-provided only that said cords K K constitute a couple as defined bythe Standard Dictionary, Ganots Physics, Deschanels Natural Philosophy,and all similar publications.

Within the outer compartment g of drum J is located a pawl-and-ratchetmechanism, which may be varied somewhat in construction, provided onlythat it is interposed between the drum and the winding-shaft of themotor in a manner to transmit power from one to the other upon eachrotation of the drum in one direction. In its preferred form ofconstruction this mechanism comprises a gravity-pawl L, pivotallysupported upon the web f of drum J, and an internal ratchetwheel M,having teeth Zaffixed to the threaded extremity d of huh I, as will beseen by reference to Figs. 3, 4, and 5. Vithiu the opposite or rearcompartment h is located a recoilspring N, its innermost end beingsecured to the drum-seat t' and its outer end fastened to a fixedsupport, such as pin m, projecting from a back plate now to bedescribed. 0 represents said back plate, constituting at once anauxiliary support for the structure, a guide for its cord or cords K,and a closure for the back or spring-containing compartment 71. Thisplate 0 is perforated centrally at P to loosely receive the tubulardrum-seat 2 It is also provided with forwardly-projecting perforatedguide-lugs Q Q, through which pass the oppositely-arranged ends ofwinding-cord K, and at its base is provided a rearwardlyprojectingangular foot R, bearing a yielding spring-tang n for insertion beneaththe end of frame B to steady the attachment.

It should be noted that the contents of compartments g h may bereversed, or both the recoil and ratchet mechanisms may be located in asingle compartment, if desired, without materially altering theirindividual or correlative action. The back plate 0 may also be varied inconstruction without in the least detracting from its generalefficiency, and

likewise various changes in the construction and arrangement of partsmay be made and substituted for those herein shown and described withoutin the least departing from the spirit of my invention as set forth inthe claims following.

Figs. 6, 7, and 8 illustrate modified forms of the invention, wherein anexternal ratchetwheel M is substituted for the internal ratchet-wheel,heretofore described,its cooperating pawl L being spring-pressed, asshown, and the back plate 0 being altered by the omission of foot B.This arrangement of ratchet and pawl is well suited to that class ofmotors wherein the Winding-shaftdoes not rotate reversely as the motorruns down. The back plate 0, however, is applicable to all types ofmotors and is so arranged that its depending feet 0 o terminate in closeproximity to the surface of base or bed plate A, where without actuallybinding they serve to steady the at taohment, which, however, is in allevents dependent mainly upon the winding-shaft of the motor for itssupport and means of attachment.

In actual construction the leading elements of my invention arepreferably stamped from sheet-steel by suitable dies; but obviously thisconstitutes no part of the present invention, since they may also becast in aluminium or other suitable material or made in any mannerwhatsoever, due consideration being given to lightness, compactness, andeconomy of manufacture.

It will he observed that the ratchet-wheel M and pawl L constitute aclutch mechanism which may be varied in construction, pro vided onlythat'a clutch is furnished which is capable of imparting to shaft H arotary motion with each initial movement of drum J and of automaticallygoing out of action with each reverse movement of the drum.

The foregoing being a description of my invention in its preferredembodiment, its use and operation may be stated as follows: Applied to aspring-motor by means of the hub Lin screw-threaded connection withwindingshaft H, as shown by Figs. 1 and 2, the invention is ready foruse. Force now applied to the cord or cords K in opposite paralleldirections, as indicated by Fig. 1, serves to rapidly rotate drum J inone direction, pawl L promptly engaging one tooth Z of ratchetwheel ll/LThe latter being thus positively driven imparts the same rotary motionto hub I and shaft H in a forward or winding direction, said hub andshaft being to all intents and purposes one and the same part. Tensionon opposite ends of the cord or cords K now being relieved,recoil-spring N, energized by the aforesaid initial rotation of drum J,goes into action to rotate said drum reversely, rewinding the cords. Inso doing pawl L is automatically withdrawn from ratchet M and comes torest in a neutral or disengaged position at the instant ringsjj at theends of cords K are stopped by their respective guides Q Q. Obviouslythen in that class of motors employing a winding shaft thatrotatesreversely as the motor force is expended the shaft H, hub I, andratchet-wheel M may continue to rotate freely, while in thatclassofmotors employing a winding-shaft that does not so rotate vreverselythe same parts will simply remain idle when drum J has come to rest.This operation of winding and recoiling may be rapidly repeated. asfrequently as desired, and it will be particularly noted that the forcethus applied to the motor-shaft as. also all moving parts of theinvention is so completely counterbalanced and distributed that strainsare reduced to a minimum and in so far as the motor-shaft is concernedare practically eliminated. This application of a pair of equal forcesacting in opposite and parallel lines upon the periphery of drum J atpointsdiametrically opposite is especially efficacious and is such thatmotors of the lightest type need not be secured inany manner to theirsupporting stands or tables during the winding operation. 7

Such being a description of my invention and ofthe preferred manner ofapplying same to practical use, whatI claim, and desire to secure byLetters Patent, 15-
